A rebound in the PC market aided Intel's earnings earlier this week, but did not help rival Advanced Micro Devices, which recorded a net loss for the second quarter, even as a shift in its business focus to graphics cards and custom chips boosted revenue.

AMD reported a net loss of $US36 million, an improvement from the $US74 million loss reported in the same quarter a year ago. Revenue in its Computing Solutions division, which deals in chips, was $669 million, declining by 20 percent year over year, due to a drop in processor shipments, AMD said in a statement.

However, AMD's overall quarterly revenue grew, aided by growth in graphics and custom chip shipments. AMD second-quarter revenue was $US1.44 billion, up 24 per cent compared to the year-ago quarter. Analysts polled by Thomson Reuters expected $US1.438 billion in revenue for the quarter.

Fearing a weak PC market for years to come, AMD has shifted its business model to focus more on adjacent markets like graphics cards and custom chips, which are part of the company's Graphics and Visual Solutions (GVS) unit. AMD is now supplying chips for Microsoft's Xbox One and Sony's PlayStation 4 gaming consoles, and has other custom chip deals in the pipeline.

Revenue for the GVS segment was $US772 million, growing 141 per cent year-over-year. Revenue for graphics chips decreased, the company said.

AMD is projecting revenue to increase 2 per cent, plus or minus 3 per cent, compared to the second quarter of 2014.

The PC market had a better-than-expected second quarter, thanks to upgrades from older Windows XP PCs. Worldwide PC shipments totaled 74.4 million PCs during the second quarter, down just 1.7 per cent from the year-ago quarter, according to IDC. The research firm said that was the slowest quarterly decline in two years. IDC had predicted a decline of 7.1 per cent.
